SEAM FOB SEWED ARTICLES.

Specification of Letters Patent.

Patented Sept. 12, 1916.

To all whom it may concern Be it known that I, ALBERT H. DE Von, a citizen of the United States, residing at \Vestfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Sea-ms for Sewed Articles, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has for its primary object to provide a simple, effective and compact seam for uniting and covering the abutted edges of fabric and particularly knit goods.

To this end the invention consists in an overseam composed of concatenated threadloops embracing a portion of the fabric, in conjunction with an auxiliary thread lying mainly upon one face of the fabric and formed with loops passing through the latter and embracing those of one of the component overseam threads at the opposite face of the fabric.

In the preferred form of the improvement, the primary thread-loops of the overseam are passed through and enter and emerge from the same face of the fabric, and the secondary thread-loops lie upon said face of the fabric and pass through and embrace different loops of the primary thread respectively at their points of entrance and emergence, while the auxiliary thread lies mainly upon the opposite face of the fabric with its loops passed through the same and embracing the secondary thread-loops intermediate their points of concatenation with the primary thread-loops.

The term overseam is used herein to (l scribe a seam which overlies a face of and embraces a portion of fabric transversely of the direction of seam-formation, and includes overedge seams applied to and embracing the edge of the work as well as seams of different nature applied to the body of the fabric intermediate the edges.

In the drawings, Figure 1 is a perspective view of sections of fabric having their abutted edges united and covered by an overseam embodying the present improvement, with certain parts of the fabric omitted to expose the component thread-loops of the seam'disposed within and beneath the upper face of the fabric. Fig. 2 is a similar view from the. opposite face of the fabric. Fig. 3 is a view similar to Fig. 1 representmg a slightly modified form of the improvement.

The pieces of fabric a and b are shown with their adjacent edges abutted together, and loops 0 of the :primary thread 0 are passed through the margin of'the fabric a in a slightly inclined direction from the lower face, across the abutted edges downwardly in a similarly inclined direction through the marginal portion of the fabric Z), terminating at the lower face of the latter. It will be observed that, while the primary thread 0 is led along the lower face of the fabric lengthwise of the seam, its loops 0" are disposed-transversely thereof and lie mainly upon the upper face of the fabric with merely their opposite end portions within the fabric. Loops cl of the secondary thread 65 are passed through the closed extremities of the primary thread-loops c and their extremities 6Z2 embrace the opposite extremities of the adjacent primary thread-loops. The threads 0 and d,'interlooped as described, together form an overseam which embraces portions of the body fabrics including the abutted edges, the points of concatenation lying upon the lower face of the fabric.

Lying mainly upon the upper or outer face of the fabrics are the auxiliary threads 6 extending lengthwise of the seam and parallel with the abutted edges of the fabric, these'threads having loops 6 extending through the fabric intermediate the crossloops .0 of primary thread and .embracing the loops '(Z of the secondary thread. As represented in the drawing, the auxiliary thread-loops c are arranged inrows which are laterally out of alinement with the extremities of the primary thread-loops 0, so that the looper-thread loops cl are notallowed to lie in a straight line betweenthe primary thread-loops with which they are concatenated, but have their end portions deflected oppositely. The thread-loops c and (Z do not lie therefore in superposed relation upon opposite faces of the fabric, but each is disposed intermediate the two adjacent loops lying upon the opposite'face of the fabric. The number of these auxiliary threads is dependent entirely upon the conditions for which the same is desired,

their function being to supplement the covering capacity of the overseam thread-loops and to prevent their displacement in the use of the garments or other articles to which the composite sea-m thus formed is applied. In Figs. 1 and 2, two of these auxiliary threads are employed at the opposite sides of the abutted edges of fabric, while in Fig. 3 only one of such threads is applied to each fabric. It will be observed that the position of the secondary thread-loops is somewhat different in the two forms of the seam, this being due to the lead of such loops to and from auxiliary thread-loops at a greater or less distance from the primary thread-loops with which they are respectively concate nated.

It is obvious that the number and arrangement of the auxiliary thread-loops will be dependent, not only upon the effectiveness of covering capacity and security of the overseam thread-loops required, but upon the width of the overseam and other conditions. As will be seen from the drawings, the portion 6 of the auxiliary thread upon the upper face of the fabric overlies and confines in position the body portions of the primary thread-loops 0, while the threadloops 6 embrace and similarly confine the secondary thread-loops (Z to the lower face of the fabric. This produces a strong, fiex ible and compact seam of which the component thread-loops are not easily permanently displaceable in the handling of the garment or article to which the improvement is applied, especially when formed of knit goods, and provides ample elasticity, in that the stretching of the goods crosswise of the joint will temporarily cause a lateral yield by straightening the secondary threadloops and drawing down the auxiliary thread-loops e to accommodate such temporary distortion, and the stretching of the goods lengthwise of the seam will also permit the drawing up of the auxiliary threadloops 6 and consequent drawing of portions of the secondary thread-loops d into the fabric. In either case the elasticity of the fabric will serve torestore the stitches to their normal condition upon the relief of the strain thereon.

It is obvious that the present improvement is susceptible of modification within the scope of the present invention, not only in the number and arrangement of the auxiliary threads but in the position and arrangement of concatenation of the overseam thread-loops, dependent in a large degree upon whether the composite seam thus formed is applied as a binding for the edge of the fabric, or as an ornamental scam in the body of the fabric (in which case the component threads may be of difierent colors), or as a means of uniting and covering the abutted marginal portions of separate pieces of fabric.

Having thus set forth the nature of the invention, what I claim herein is 1. In a seam for sewed articles, the combination with a fabric, of an overseam composed of concatenated threads having loops embracing a portion of the fabric, the loops of one of said threads lying mainly upon one face of the fabric, but having portions entering the fabric, and an auxiliary'thread lying mainly upon the same face of said embraced portion of fabric and having threadloops passing through the fabric and embracing loops of another of the component threads of the overseam.

2. In a seam for sewed articles, the combination with a fabric, of primary threadloops entering the same from one face and emerging therefrom at the same face, secondary thread-loops lying upon said face of the fabric and passing through said primary thread-loops adjacent their points of emergence from the fabric and embracing other primary thread-loops adjacent their points of entrance, and an auxiliary thread lying upon the opposite face of the fabric and formed with loops passing through the fabric and embracing the secondary threadloops.

3. In a seam for sewed articles, the combination with a fabric, of a primary thread formed with loops entering the same from one face and emerging therefrom at the,

same face, a secondary thread lying upon said face of the fabric and concatenated with the loops of the primary thread at their points of entrance and emergence from the fabric, and a plurality of auxiliary threads lying mainly upon the opposite face of the fabric and formed with loops passing through the fabric at points out of lateral alinement with the points of entrance and emergence of the primary thread-loops and embracing the secondary thread intermediate its points of concatenation with the primary thread-loops.

4:. In a seam for sewed articles, the combination with two abutted edge-portions of fabric, of two cross threads lying mainly on opposite faces of the fabric, each cross thread being formed into loops extending across the line of division between the fabrics, substantially at a right angle thereto, and engaging the other thread, and two lon gitudinally disposed threads engaging loops of each cross thread and binding them to the loops of the longitudinally disposed threads to key the same, and another cross thread having loops extending through the loops of the first cross thread through the fabric, and crossing the line of division between the abutted edges.

6. In a seam for sewed articles, the combination with a fabric, of four longitudinally disposed threads lying mainly along one surface of the fabric and having loops entering the fabric a cross thread lying on the other surface of said fabric and passing through said loops to key the same, a second cross thread lying mainly on said first mentioned surface of the fabric but having portions extending through the fabric and engaging the first mentioned cross thread.

7. In a seam for sewed articles, the combination with fabric, of four longitudinally extending threads lying mainly on one surface of the fabric and having loops entering the fabric at intervals, a cross thread lying along the other surface of the fabric and formed into loops, each loop having two substantially straight limbs extending substantially at a right angle to the line of seam-formation and through a loop in each of the longitudinally extending threads, and another cross thread lying mainly on the first mentioned surface of the fabric and keyed to said loops of the first mentioned cross thread.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
